Summary
Boarding Action is a multiplayer map in Halo 1. There are two parallel human battleships similar to the Pillar of Autumn. In addition, there are 4 teleports on both ships, two on the first level, and two on the fifth level. This map is usually pick by hosts for its exciting sniper battles. Other hosts may turn off sniping to force players to board the other ship. This usually results in a frenzy of explosions near each teleporter as each team franticly trys to stop the other team on thier ship.
An interesting way to simulate ship-to-ship combat is to do a 4-Xbox system link, and have 16 players, eight to a team, loaded with all Rocket Launchers. Volleys of rockets across the two ships greatly resemble hot exchanges of cannon fire between two eighteenth-century ships-of-the-line. It is not at all uncommon in any gametype to find yourself standing directly above or below an enemy as the ships have several floors, with each floor number marked on the wall. Often times one player will come through a teleporter right in to another player whithout much warning. Should you fall into the space between the two ships, obviously you will die, but after falling a certain distance, you hit an invisible floor, for lack of a better term.
